  • Froth Flotation of Iron Ores

    With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

  • Effect of sulfur dioxide on flotation of chalcopyrite

    Another potential purpose for using sulfur dioxide in sulfide ore flotation might be to replace sodium cyanide as suggested by Miller (1970). The existing literature on the use of sulfur dioxide in complex sulfide mineral flotation does not provide a satisfactory explanation of the mechanisms by which it influences the hydrophobicity of chalcopyrite.
